Hi Rishabh.

*tested() don't do anything, they are meant to keep track of which parts
of the code are covered by some tests. it's probably best to start any
new code fragment with an "untested();" call.

the parser has a cursor that represents how much of a line has been
parsed (from left to right) already. tail() returns the part right of
the cursor, more() tells you, whether that right part contains
non-whitespace.
